I changed "sensitivity=100" from dosbox.conf to different values but that didn't help.
For example, i lowered it to "10", as a result the mouse would still jump from one end of the screen to the other, but now it would do it in slow motion. The mouse would behave as if in "dream state" 😀
Its probably a problem in the way dosbox reads my mouse movement.... (at this point i can hear all the dosbox developers rushing to say that dosbox has no problems and that its my fault) 😀🤣
As they're using the relative mouse motion fields as well, i guess
the SDL_MouseMotionEvent->xrel and ->yrel is messed up on your system.
You can try to output the fields of the motion-variable in
HandleMouseMotion() of sdlmain.cpp
Well i don't know, but i assume it is as two different programs are affected.
You could test that by modifying the sources, maybe somebody else with
the same system could do that as well.
Do regular 32bit x86 compiles work? Maybe i can send you
a build that displays some information about the mouse
SDL events.
Guess that the SDL people would be interested in knowing
about it if there's really a bug.
Please try it with =directx as well (as in some cases dosbox will fall back
to windib by default).
Do the output= settings make any difference? Or changing fullresolution=
to various values?
